Wire Rope Sheaves

Pfaff wire rope pulleys with sheave diameters from 80mm to 490mm and rope diameters from 6mm to 18mm.

The sheaves DSR made of steel provides a safe concept due to a wear-resistant rope guide where the machine groove is perfectly adjusted to the wire rope. There are 15 different types guarantees that are at a made-to-specification solution at loads of up to 8 tons. The sheaves can be varied in wire and sheave diameter (from 80 up to 490 mm) and as standard all sheaves are equipped with ball bearings.

McKissick® Tapered Bearing Sheaves are designed to operate on shafts machined to +/- .0005 of the indicated shaft size. Applications should provide for tightening separator plates against bearing cones to adjust and insure proper function of bearing. For sizes not listed, McKissick® Finished Bore Sheaves can be equipped with tapered Bearings at an addtional charge.

The McKissick Stepped hub eliminates stress failure in the weld, common in normal hub designs. The hub is pressed into place with complete metal-to-metal contact. This helps ensure an accurate alignment to the hubs axis so there's no wobble or lopping of the rotating sheave.

McKissick Finished Bore Sheaves can be equipped with bushings or bearings at an optional charge. Roll Forged sheaves are available in sized up to 72" in diameter. 14" diameter sheaves and larger are Roll Forged with Flame hardened grooves to minimum Rockwell 35C.

McKissick Roller Bearing Sheaves.
Roll Forged™ sheaves are available in sized up to 72" in diameter. McKissick® Roller Bearing Sheaves are designed to operate on shafts carbonized to 660 Rockwell "C" and ground to +/- .0005 of the indicated shaft size. Some sizes are available with an optional inner race. For sizes not listed, McKissick® Finished Bore Sheaves can be equipped with roller bearings at an additional charge.
